DAX and RX streams question

I have a question about DAX Control panel.If I open more than one panadapter or add a Slice receiver, I only see Slice A in DAX control panel.While i can listen other panadapters , I just would like to understand the DAX control panel.Could soneone clarify it for me, please .Here is example below.ThanksSergey, KN7K

If you select a DAX channel on the slice B flag, you will then see that Slice B is identified as the source for that channel in the DAX control panel. You must select a DAX channel in the slice flag or nothing can show up in the control panel.
